weston: add dependency on virtual/libgbm for kms PACKAGECONFIG

* gbm is checked in configure.ac:

AC_ARG_ENABLE(drm-compositor, [ --enable-drm-compositor],,
enable_drm_compositor=yes)
AM_CONDITIONAL(ENABLE_DRM_COMPOSITOR, test x$enable_drm_compositor = xyes)
if test x$enable_drm_compositor = xyes; then
AC_DEFINE([BUILD_DRM_COMPOSITOR], [1], [Build the DRM compositor]) PKG_CHECK_MODULES(DRM_COMPOSITOR, [libudev >= 136 libdrm >= 2.4.30 gbm mtdev >= 1.1.0]) PKG_CHECK_MODULES(DRM_COMPOSITOR_GBM, [gbm >= 10.2],
[AC_DEFINE([HAVE_GBM_FD_IMPORT], 1, [gbm supports dmabuf import])], [AC_MSG_WARN([gbm does not support dmabuf import, will omit that capability])])
